Quotebook isn't meant to be an app you use every day. It's meant to be perfect when you need it, like all the times you wish you remembered that astute Albert Einstein quote. Quotebook doesn't ship filled with quotes but instead challenges you to type out a collection of great ideas and thoughts you've seen and heard. The idea is far from a novel one — books of quotes have been published for as long as people have carried pocket notebooks to scrawl down things they like. The $2.99 universal app launches for iPad today, joining its iPhone brethren and syncing all your favorite proverbs and axioms through iCloud.

Quotebook isn't just for data entry, however. When you type in a quote's author, tapping a blue arrow immediately takes you to WIkipedia (inside the app) to learn more about him or her. A tab near the top of the screen jumps you between the author's Wikipedia page and a Wikiquote page filled with quotes by that person. If you're browsing Wikipedia or Wikiquote within the app and copy text, it intelligently asks if you want to add that text as a quote to your library, correctly attributed and all. Once your library is chock full of inspirational nuggets, you can browse by date added, author, source (like Walden), tag (like "life lessons"), and via a quick search field. You can share posts to Twitter, Facebook, and Tumblr with a couple taps. Conversely, Quotebook worked with Instapaper to let you add highlighted text straight from the popular read-later app.

While some may ridicule the app's leather-bound skeumorphic design inspiration, we think it looks understated, elegant, and unobtrusive. The app isn't trying to bite off more than it can chew, and it "just works," so of course it only makes sense that developer Lickability is named after a Steve Jobs quote. "We made the buttons on the screen look so good you'll want to lick them," the company pasted on its homepage. You won't want to lick your iPad once you install Quotebook, but the app's pretty useful for a few bucks.
